The ability of B-mode ultrasound to follow effectively blood clot echogenicity changes over time under conditions of red cell preservation and lysis was evaluated. Blood clots were produced in cellulose dialysis tubing and then placed into appropriate baths of either saline or water. The echogenicity changes were then followed quantitatively using A-mode and qualitatively using B-mode imaging. Blood clots in saline showed an initial decrease followed by a leveling off in echogenicity. Blood clots in water showed a decline in echogenicity throughout the experiment. The A-mode imaging was effectively able to follow blood clot echogenicity changes under these controlled conditions.
评估了B超在红细胞保存和溶解条件下随时间有效追踪血凝块回声性变化的能力。在纤维素透析管中产生血凝块,然后将其置于生理盐水或水的适当浴液中。然后使用A型模式定量追踪回声性变化,并使用B型成像进行定性追踪。盐水中的血凝块回声性最初下降,随后趋于平稳。整个实验过程中,水中的血凝块回声性呈下降趋势。在这些受控条件下,A型成像能够有效追踪血凝块回声性变化。
